Magnetic Bars

Magnetic bars are the most simple permanent magnetic separators, they are magnets assemblies which composed of permanent magnets and stainless steel tube. They also called as magnetic filter bars. In side of magnetic bars filled with super strong rare-earth magnets or ferrite magnets as magnetism source, the surface covered with 304 steel tubes of 316 steel tubes, the two ends sealed and welded. The magnetic strength range for each magnetic bar is 1500Gs-12000Gs.

The magnetic bar separators can separate the tiny metal impurity from the materials, then protect the downstream equipment from damage and improve the purity of the material. The magnetic bar is the smallest magnetic separator unit that can be single used, it can also be used as basic element magnetic grate separators/magnetic grid separators, drawer magnetic separators, liquid magnetic separator, and rotary magnetic separators etc.

The structure features of magnetic bars:
1. Extreme strong magnetic force, the surface magnetic field power can be up to 12000Gs for the magnetic bars with the diameter of 25mm.
2. The surface of the magnetic bars are sealed and welded by stainless steel-304, stainless steel-316 or stainless steel-316L, and with polishing treatment, it can be used to treatment powder or liquid material.
3. With polishing treatment on the surface, the magnetic bars is meet the requirement of food safety grade.
4. The diameter and length of the powerful magnetic bars can be made according to customer’s need, the common diameter of the magnetic bar is 25mm(1”), the maximum length for the magnetic bar can be made up to 2500mm for the diameter 25mm.
5. The strong magnetic bars are usually made as round shape, square shaped magnetic bars also be made out.
6. The maximum working temperature of the normal magnetic bars is 80℃, it can also be made for more higher working temperature according to clients need.
7. To make it easy to be fixed, both ends of the strong magnetic bars can be made with threaded holes, hand rings, screw thread and tapered tip.

Please provide below information when you order or inquiry the magnetic bar separators.
1. the size of the magnetic bars which including the diameter and length.
2. the maximum working temperature of the magnetic bars.
3. the magnetic force or magnetic strength of the magnetic bars.
4. the designs for both ends(whether need screw thread, threaded hole and rings or not).
